Given:

The wavelength of highly energetic ultraviolet radiation is 125nm.

To Find:

The frequency of highly energetic ultraviolet radiation has a wavelength of 125 nm.

Solution:

Frequency is the inverse of the period (t) and it is the number of oscillations per unit time or is the number of repetitions of an event by an object per unit time.

Frequency can also be calculated in terms of wavelength and speed of light.

The formula for frequency is given by the equation:

frequency =  \frac{c \:(in \: ms - 2)}{wavelength \: in \: m}

Here,

c = speed of light in ms-2 = 3× 10

wavelength = 125 × 10-9 m

Now,

Putting the values we get,

frequeny \:  =   \frac{3 \times  {10}^{8} }{125 \times  {10 }^{ - 9} }

 = 2.4 \times  {10}^{15}  {s}^{ - 1}

Henceforth, the frequency of highly energetic ultraviolet radiation that has a wavelength of 125 nm is 2.4×10 15 s −1
